INTRODUCTION:
In this fast generation, the human has no time for anything. He is completely busy with his personal work and totally devoted himself to the so called computers or laptops. A common man usually prefers his own transport to go to office or work. On the roads, they sometimes go against the traffic rules, jump the traffic signals etc. He mainly does all this kind of odd activities to reach the office on time. Thus, it takes a good amount of time for us to realize that we need to help others mainly the patients in the ambulance. We merely bother about them and do not give space to the ambulances so that they reach the hospitals soon and will be saved out of danger. Thus, this project is designed to clear the traffic and provide a way to the ambulance so that the patient can be saved upto the maximum extent.
The project uses RF technology to implement this application. The ambulance will be fixed with the RF transmitter and the RF receiver will be fixed at the traffic signals. This transmitter transmits a unique code continuously into air. When the ambulance is near to the traffic signals, the unique code, transmitted by the transmitter from the ambulance, will be received by the RF receiver at the traffic signals.
The controlling unit, after receiving the data from the RF receiver operates the traffic signals so as to allow the ambulance to move on without stopping it i.e., the green signal will be given for a long time so that the ambulance cannot be caught in the traffic. This green light will be given until the output of the RF receiver changes. The output changes when the RF receiver does not receive any input from the transmitter. After the ambulance has passed away, the traffic signals will be operated as usual.
